High-wattage ATX 3.0 power supply

The MSI MEG Ai1300P PCIE5 delivers 1300 W through a single +12 V rail and meets ATX 3.0 and PCIe 5.0 specifications. It targets builders running flagship graphics cards such as the 4080 or 4090 and workstations that demand sustained high loads. The 80 PLUS Platinum rating confirms up to 92 % efficiency at typical loads.

Full-modular installation with 150 mm depth

A full-modular cable set lets you connect only the leads you need, including eight 6+2-pin PCIe connectors, 16 SATA plugs and the 12VHPWR cable for modern GPUs. The 150 mm chassis fits most mid-tower and larger cases, but compact builds should verify clearance. Sleeved cables improve routing but add stiffness; plan bends before tightening screws.

Check GPU power needs and case length

Confirm your graphics card requires the 12VHPWR connector or multiple 6+2-pin leads before ordering. Measure the available PSU bay depth against the 150 mm unit length. Ensure the motherboard accepts a 24-pin main connector and that the 100-240 V input range matches your local mains supply.

Perguntas sobre este artigo

How can I confirm the PSU is delivering stable power after installation?

The power-good signal triggers between 100 ms and 500 ms, showing the rails are within spec; the single +12 V rail design and 80 PLUS Platinum efficiency up to 92 % also indicate correct operation.

Which cables come in the box and what must I source separately?

The full-modular unit includes a 24-pin ATX connector, eight 6+2-pin PCIe connectors, sixteen SATA power connectors and a 12VHPWR cable for PCIe 5.0 graphics cards; no extra cables are required for standard builds.

Which capacity should I pick for a system with a 4080 or 4090 class GPU?

The 1300 W Platinum model is ATX 3.0 and PCIe 5.0 ready, providing ample headroom for a 4080 or 4090 plus other components while maintaining high efficiency and low noise.
